To all whom, it may concern:

Be it known that we, FREDERICKGEORGE N IND, a subject ofthe King of Great Britain and Ireland, and FREDERICK JULYAN, a citizen of the United 'States, residing at Cleveland, in the county of CuyahOga and State of Ohio, have invented a certain new and useful Improvement in Paper-Feeding Mechanism, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of this invention is to provid an efficient means for feeding paper, enabling sheets to be successively dislodged from a block of paper. The invention relates, particularly, to the means by which such feeding mechanism may be easily and quickly adjusted to receive and hold blocks of size, varying thickness, stiffness and weight of the sheets and varying amounts of mois-v ture carried thereby, and to present such paper in such a way as will enable successive sheets to be conveniently dislodged and acted upon.

nism.

The present application is a division of' our application No. 471,138, wherein a complete folding machine having the present feeding mechanism is shown and described.

In accordance with the above, ourinvention may be most conveniently summarized as consisting of the combinations of cooperating element's hereinafter more fully explained and set out-inftheclaiins.

In the drawings, Figure-1 is-a side 'eleva= tion of our feeding mechanism; Fig. 2 is an f enlargeddetail, being a perspective view of the means employed to permit the follower plate to be adjusted on its pivots; Fig. 3 is a detail, being a vertical section through the lower end of the means which support the swivel rod of the follower plate; Fig. 4- is an end view ;of--the machine showing, more particularly, the; follower plate and the de- I yiceeoemployed for adjustably securing it in plane through the follower and the section paper of varying Our invention is particularly well adapted cross-bar 28.

position; Fig. 5 is an enlarged detail, being a sectional side elevation of the folplane of thegshaft 45 being in front of the plane on which the shafts 31 and 32 are out. Referring to the several figuresof the indicated by like reference characters z-20 indicates the supporting standards, a pair of such belng provided at each side of the machine and each pair having at their upper ends one of. the 'longitudinallyaextending side bars of the frame of themachine, such side-bars being indicated by 21. 'Each of these side-bars is providedwith upwardlyextending lugs 22 in which are secured bars 23 upon which is slidably mounted a frame 24:, to which frame is-adjustably secured in the manner hereinafter specifically described, a' follower plate 25, said followerplate consisting as shown of 2. depending vertical portion and a rearWardly-inclined upper portion. The follower-plate is adapted to press against a pile of sheets of paper so as to hold said pile in position to be engaged by suitable mechanism, as, for example, the set of folding rolls'shown which and impart an initial fold thereto. This follower-plate is held against the sheets with the required degree of pressure by a pair of coiled springs 26 secured at their forward ends to the-fixed frame of the machine and at their other or rear ends to across -bar 27 that is adjustably held in any one of a series of notches in the side-bars of the sliding frame 24, as clearly shown in Fig. l.

The side-bars 21 of the supporting frame are connected near their forward. ends by a 'Atopposite sides of the supporting frame, are projecting brackets 29 to which maybe secured a-framework carrying mechanism (not shown) for imparting additional folds to the sheets or other operations desired. The primary folding and dislodging mechanism shown will be described after we have described the devices for permitting ,the varying adjustments of the feeding mechanism. p In apparatus of this character, it has been found that it 'is essential to provide means ways so as to perfectlyacoommodate it to different kinds of. paper and to varyingab mospheric conditions, 'w ich, as is well known, will affect a pile of sheets invarious ways. It i's'neces'sary in some instances to for adjusting the follower-plate invariousi drawings, in which corresponding parts are l are adapted to dislodge the foremost sheet in farther than the other portion; and it is also desirable that the follower-plate be ad justable vertically up and down as a whole,-all of these adjustments being provided for in our machine.

The cross-bar portion of the sliding frame 24 (see Fig. 4) is provided with two down-.

wardly-extending ears 57 and 58, the ear 57, in the construction shown, being much shorter than the ear 58. These ears are each placed a short distance from the center of the cross-bar of the sliding frame 24. Between these two ears 57-58 fits an arm 59 havinga horizontal head portion-60 at its upper end that substantially fills the space between the two ears 5758 and this device is pivotally suspended on a pin 61 that passes through it and through said ears. From the head portion 60 at one side depends a piece 62 that lies close to the inner face of the long ear 58, which piece 62 is enlarged at itl ver end and-provided with a slot 63 through which a headed bolt 64 passes, the bolt also projecting through the long ear 58 and being adapted to have screwed upon it a thumb-nut 65. By, this construction it is evident that the arm 59 can be swung as desired upon its pivot pin 61 and held in any desired position by turning up the thumb-nut 65.

6 indicates a heavy rod suitably secured to the under face of the inclined portion of the followerplate 25. This rod passes through and fits snugly in two eyes 67 and 68 that are formed with an arm 69 that lies over the arm 59. The arm 69 is pivotally connected at its lower end to the lower end of the arm 59, the pivot being indicated by 66", and at its upper end behind the upper eye 67 it is provided with two ears 70 that lie against the head portion 60 of the arm 59, said ears being provided with short slots 71 through which pass set screws 72 that enter suitable screw-threaded holes in said head portion 60. This construction obviously permits, when the said set screws 72 are loosened, a slight lateral adjustment of the arm 69 so as to move the rod 66 and the followenplate carried thereby toward one side or the other of the machine, in which adjusted position it can be set by the turning of said set screws 72.

The rod 66 is provided with a collar 73 that is adjustably secured to it, preferably by means of a set screw, as shown in Fig. 2, and upon the location of this collar on the said rod depends the extent to which the rod can move downward in its said eyes 67-68.

74 indicates two screws that pass through holes in the cross-bar portion of the sliding frame 24, each of, said screws being located asshown in Fig. 4 about midway between one side bar of said frame and the center of the crossbar portion thereof. These screws are adapted to be pressed against the face of the vertical portlon of the follower-plate and by screwing up one screw a little more than the other the follower-plate can be turned slightlyon its rod 66 as an axis so as to press more tightly toward the folding rolls 3031 at one side than at the other.

By the construction described, it will be seen that the follower-plate can be raised or lowered, as desired, and held in its adjusted vertical position by securing the collar 78 to the rod 66; that the follower-plate can be swung slightly on the horizontal pivot pin 61 and can be secured after being swung to the desired position by means of the thumb-nut 65; that it can be given a slight side swing on the pivot 66 and secured after bein so swung by setting the screws 7 2; and tl at one side of the vertical portion of the follower-plate can be advanced slightly closer to the folding rolls 3() 31 than the other by proper adjustment of the-screws 74,all of which adjustments permit an almost universal movement of the follower-plate to adapt it to all kinds and conditions of sheets and climatic changes which affect the free movement of said sheets.

75 indicates two vertical rackbars secured in any suitable manner to the rear face of the cross-bar 28 of the supporting frame, and 76 indicates another bar but without the teeth of the bar 7 5, said bar 76 being also secured to said cross-bar 2S and being located between the two rack-bars 75. The upper ends of these bars extend almost to the plain metal roll 31. These three bars serve to hold the pile of sheets in a ver carries at one end a pinion S1 suitably aflixed to said rod and adapted to mesh with the rack bar. This rod is provided at its outer end with a wheel or handle 82 by the turning of which the rod 80 is rota-ted, and,

through the engagement of the pinion 81 with its rackebar, the rod and its attached supporting arm 77 are moved up or down on of the follower plate results from the said rack-bar. When the desired position has been reached, the device is clamped in that position by means of a small set screw 83 that passes through a horizontal lip 84 and bears against the hub of the wheel or handle 82. j I

As shown in Fig. 4, the vertical portion 25- straddles the 'supporting arms 77 by reason of two vertical openings or slots in the follower plate. These openin conveniently extend from the bottom e ge of the follower plate. It

these openings in the follower piateaand from the length of the arms'77 that these membersintersect each other for various-positions of the arms and the follower plate. Accordingly, there is a wide latitude in the amount. of paper which maybe on the supports, while by these adjustable supports, the pile of paper can beheld 'in proper position so that thecentral portion of each sheet, or that portion across the sheet to which it is desired to impart the primary fold, will be properly presented to the said folding rolls -31.

Referring now to the dislodging and primarily folding niechanism shown herein, the roll 31 is preferably a smooth surface, while the roll- 30 is made of yielding material. At one end the shaft 33 of the smooth roll 31 is extended and has secured thereon a suit- ;able driving pulley 34 and at its other end it has a pinion 36 indicates a rocking frame consisting of a bar extending parallel with the smooth roll 31 and pivotally hung from the shaft of such roll by blocks 37 (see Fig. 5) formed. with such bar. 38indicates bearings for the shaft 32 of the yielding roll 30, which bearings have depending lugs 39 that fit in suitable openings in the said blocks 37 and are held there by set screws 40. By this means of supporting the "shafts 32, the-roll can be slightly adjusted closer to or farther from the smooth roll 31, as required, and secured in the proper adjusted position by. the said set screws 40. This construction also admits of the ready detachment of the shaft 32' to permit the changing about'or the renewal of the sections of the roll 30, as may be required.

" 41 indicatesa gear rotatable upon a short stub-shaft 42 projecting out from one side 1 of the main supporting frame, said gear-being in mesh with the pinion 35 on the shaft 33. On the same stub-shaft 12 and secured to the face of the gear 41 is a pinion .43 which meshes with a large gear 44 rotatably mounted upon a stub-shaft This gear 44 has attached to its outer'faceso that it will. move with such gear a cam 46 (see Fig. 5) upon the surface of which cam rests an arm 47 that projects into ahollow block 48 and is adjustably secured in any desired position by means of a set screw 4-9.- This against a rigid downwardly extending arm 56 that is secured at its upper end to a projecting portion of the frame 36 that is journaled on. the shaft 33 and supports. the shaft of the yielding roll 30. From the construction described, it will be seen that as the shaft. of the roll 31 is rotated, when power is applied to it throu h the pulley 34, the gearing described will cause a rotation of the cam 46 on the stubshaft 45 and such cam will, through the arm 47, cause a turning of the rock-shaft 51,- and, as this takes place -y-the arm 52 will be moved and forced forward the arm 56, causing the frame 36to turn on its pivotal support and bring the yielding roll 30 more directly over the plain smooth-roll 31 so that such yielding roll will be in the dotted lines in Fig. 5 and willengage the outermost sheet of the pile of sheets to be folded, causing such sheet to buckle and pass -between the two. rolls 30-31, said former .roll. being constantly driven of courseby the engagement of its gear with the pinion 35' on the positively driven shaft 33. The extent to which the yielding roll 30 will be moved toward-the screw 54:- The provision of' the swinging plate 55 with which such screw engages serves to take up wear and to apply the pressure better than if the screw impinged directly against the rigid arm 56.' v
